While caring for a client receiving total parenteral nutrition (TPN), it is most important for the nurse to monitor which of the client's lab values?

Urinary ketones.

Serum protein.

Serum osmolarity.

Capillary glucose.

Answer and Explanation

The Correct Answer is C

Choice A

Urinary ketones are not most important. Monitoring urinary ketones can provide information about the utilization of glucose and fat as energy sources. However, it is not the primary lab value to monitor in TPN administration.

Choice B

Serum protein is not most important. Monitoring serum protein levels is important to assess nutritional status, but it might not be as immediate a concern as serum osmolarity.

Choice C

Serum osmolarity is the most important. When caring for a client receiving total parenteral nutrition (TPN), monitoring serum osmolarity is most important. TPN is a highly concentrated solution containing various nutrients, and it is infused directly into the bloodstream. Serum osmolarity reflects the concentration of particles (such as electrolytes, glucose, and other solutes) in the blood. Monitoring serum osmolarity is crucial to prevent complications related to fluid and electrolyte imbalances that can arise from the administration of TPN.

Choice D

Capillary glucose is not the most important. Monitoring capillary glucose levels is important, especially in clients receiving TPN with added glucose. Hyperglycaemia is a potential complication of TPN. While glucose monitoring is important, it is secondary to monitoring serum osmolarity, which encompasses a broader range of solute concentrations.

Correct Answer is D

Explanation

Choice A

Bananas are incorrect. While bananas contain some nutrients, they are not significant sources of vitamin D, calcium, or phosphate, which are key nutrients for preventing rickets.

Choice B

Apple juice is incorrect. Apple juice is not a significant source of vitamin D, calcium, or phosphate. It may contain some vitamins and minerals, but it is not a primary food source for preventing rickets.

Choice C

Oranges are incorrect. Like bananas and apple juice, oranges are not significant sources of vitamin D, calcium, or phosphate. While they contain vitamin C, which is important for overall health, they are not the best dietary source for preventing rickets.

Choice D

Fortified milk is correct. Rickets is a condition primarily caused by a deficiency of vitamin D, calcium, or phosphate. Vitamin D is crucial for the proper absorption of calcium and phosphorus in the body, which are essential for bone health and development. Fortified milk is an excellent dietary source for preventing rickets because it is often enriched with vitamin D and calcium, both of which are important for bone mineralization and growth.

A. Potatoes, bananas, and oranges. B. Cranberry juice, butter, and hard candy. C. Milk products, canned salmon, and fresh oysters. D. Hard cheese, whole grain cereals, and dried vegetables.

Correct Answer is A

Explanation

Choice A

Potatoes, bananas, and oranges should be encouraged. Hypokalaemia refers to a lower than normal level of potassium in the blood. Potassium is an essential mineral that plays a crucial role in maintaining proper muscle function, nerve signalling, and fluid balance in the body. To address hypokalaemia, it's important to consume foods that are rich in potassium.

Choice B

Cranberry juice, butter, and hard candy. None of these foods are particularly high in potassium should not be encouraged. Cranberry juice is more commonly associated with urinary tract health, and butter and hard candy do not contribute significant amounts of potassium.

Choice C

Milk products, canned salmon, and fresh oysters should not be encouraged. While milk products contain some potassium, they are not as potent a source as other options. Canned salmon and fresh oysters do provide some potassium, but they are not as well-known for their potassium content as other foods like bananas and potatoes.

Choice D

Hard cheese, whole grain cereals, and dried vegetables should not be encouraged. These foods are not known for being particularly high in potassium. Hard cheese and whole grain cereals have limited potassium content, and dried vegetables, while containing some potassium, are not among the best sources.
